As electronics systems technicians, we are often asked for unique solutions for doorbells, gate triggers, lighting control, etc. On this project, we were asked to design and install our first fish fan. The tank pictured is a salt water aquarium with artificial sun lights (that get the area hot!).
Normally, this is not a problem, but the design of the room required that a the cabinet be installed over the tank. This of course, prevents any of the heat from the lamps from escaping and risks cooked fish! All of our entertainment system designs include active thermal ventilation (fans), so the builder gave us a call and asked for a similar solution.
We wound up installing a remote-mount impeller-fan unit in the attic with a 4 inch intake located directly above the fish tank. We routed the exhaust hose through the attic and through an interior attic wall to an area above a screened porch that had vent holes in the eaves. We did not directly vent into the attic space as the house was engineered to require no airflow through the attic and our fish fan would have caused potential heat and humidity problems.
